3 GENERAL INTRODUCTION Thank you for selecting the 3010M meter. The 3010M is a precision tool that measure conductivity, salinity, TDS and temperature. A built-in microprocessor stores, calculates and compensates for all parameters related to conductivity and temperature determinations. This unit has a waterproof IP65 case. The touch mode keys are highly reliable with tactile and audio feedback. This meter can operate with one 9V battery. Re-calibration is not required when power is restored. The front of the meter has a large LCD that displays temperature and either temperature compensated or non-temperature compensated conductivity, salinity or TDS simultaneously along with user prompts and mode indicators. The unit prompts the user through calibration and measurement procedures. The unit is also equipped with a non-volatile memory allowing the user to store 50 different sets of readings. This unit will assign a site number for each set of reading so the user can review the data easily. The model 3010M is available with three two-wire conductivity cell (K=0.1; 1.0; 10.0). Other features include automatic conductivity ranging, automatic temperature compensation, long battery life, and 50/60 Hz AC noise rejection. This unit is universal and user-friendly for field, industrial and laboratory applications. INITIAL INSPECTION Carefully unpack the unit and accessories. Inspect for damages made in shipment. If any damage is found, notify your Jenco representative immediately. All packing materials should be saved until satisfactory operation is confirmed. WATER PROOF Though the 3010M meter is housed in a watertight case, DO NOT use it underwater. The watertight case prevents permanent damage to the unit if accidentally dropped into non-corrosive solutions. Follow these steps immediately if the unit is immersed in any solution: 1. Rinse unit carefully with distilled water. After rinsing and drying, inspect and clean connectors to remove all contaminants that may affect probe connections. 2

9 OPERATIONAL PROCEDURES A. Preparing Standard Solutions Suitable conductivity standards are available commercially or the user can prepare them using research grade reagents. Here are some standard solutions the user can prepare to calibrate the probe of the model 3010M. 1. Standard solution of 1413uS at 25 : Accurately weight out grams of research grade dried Potassium Chloride (KCL). Dissolve in 1000ml of distilled water. 2. Standard solution of 12.90mS at 25 : Accurately weight out grams of research grade dried Potassium Chloride (KCL). Dissolve in 1000ml of distilled water. 3. Standard solution of 111.9mS at 25 : Accurately weight out grams of research grade dried Potassium Chloride (KCL). Dissolve in 1000ml of distilled water. 4. Standard solution of 147uS at 25 : Accurately measure out 100ml of the 1413uS standard solution as in point 1. Dilute it with 900ml of distilled water. 5. Standard solution of 14.94uS at 25 : Accurately measure out 100ml of the 147uS standard solution as in point 4. Dilute it with 900ml of distilled water. [Note: The user can store the remaining solution in a plastic container for one week but the air space between the cap and the solution must be kept to an absolute minimum. Storing the excess solution below 4 can increase the storage life. If you have any doubt of the accuracy of the stored solution, a fresh batch should be prepared.] B. Calibration Calibration setup contains five parameters: TDS, Cell, Temperature Coefficient, Temperature reference and Conductivity Calibration. To access these sections: 1. Connect the conductivity probe either the 109A (K=0.1) or the 106A (K=1.0) or the 107A (K=10.0) to the unit and turn the unit on. The screen will display the CELL icon and the cell constant of the previous calibration. (Factory default is set at K=1.0). 8

10 2. Allow temperature reading to stabilize, press CAL key to enter the calibration mode. The CAL icon appears on the LCD. Press MODE key to sequentially view previous calibration settings. TDS TDS is determined by multiplying conductivity (ms) by a TDS factor. The default factor value is To change the TDS factor, use the UP and DOWN keys to adjust the value between 0.30 and Press ENTER key to save the new value and the unit will automatically go into the next calibration parameter. If MODE key is pressed instead of the ENTER key, any changes made will be cancelled and the previous calibration settings will be retained. CELL Use UP and DOWN keys to select cell constant between C0.1 or C1.0 or C10.0 on the secondary display. Press ENTER key to confirm selection and the unit will then automatically go into the next calibration parameter. If MODE key is pressed instead of the ENTER key, any changes made will be cancelled and the previous calibration settings will be retained. Temperature Coefficient The unit uses the temperature coefficient to calculate temperature compensated conductivity. The default value is 1.91%. To change the temperature coefficient, use the UP and DOWN keys to adjust the value between 0 and 4.00%. Press ENTER key to save the new value and the unit will automatically go into the next calibration parameter. If MODE key is pressed instead of the ENTER key, any changes made will be cancelled and the previous calibration settings will be retained. Temperature Reference The unit uses the temperature reference value to calculate temperature compensated conductivity. The default value is 25. To change the temperature coefficient, use the UP and DOWN keys to adjust the value between 15 and 25. Press ENTER key to save the new value and the unit will automatically go into the next calibration parameter. If MODE key is pressed instead of the ENTER key, any changes made will be cancelled and the previous calibration 9

11 settings will be retained. Conductivity Calibration (a) Immerse the probe in a standard of known conductivity, preferably a standard in the middle range of the solutions to be measured. Immerse the probe (at least 2 to 3 or 5~7cm from the tip) into standard solution without touching the sides of the calibration container. Shake the probe lightly to remove any air bubbles trapped in the conductivity cell. (b) Allow temperature to stabilize. The message rage (range) may appear briefly on the display indicating auto-ranging; this is normal. After temperature stabilization, use the UP and DOWN keys to adjust the conductivity value to that of the conductivity standard at 25. Press ENTER key to calibrate. The unit beeps to indicate a successful calibration. Calibration is now complete and the unit will automatically switch to Measurement mode. C. Conductivity Measurements 1. Turn the unit on. Place the probe in the solution to be measured. Immerse the probe (at least 2 to 3 or 5~7cm from the tip) in the sample solution. Shake the probe lightly to remove any trapped air bubbles in the conductivity cell. 2. Press MODE key to enter into the desired measurement mode. The message rage (range) may appear briefly on the display indicating auto-ranging; this is normal. Allow temperature to stabilize. D. Save, Recall and Delete Data a. Saving readings to memory. 1. In compensated conductivity, salinity, total dissolved solids (TDS) and uncompensated conductivity modes, press the ENTER key to save data. The Save icon with the corresponding site number will lit up for a brief moment to indicate a successful data save. 2. If the Full icon is displayed, this means that all 50 data saving sites are used up. No new data can be saved until existing saved data are deleted. 10

12 b. Recalling readings from memory. 1. To recall saved data, press ENTER key at the Recall interface to go into Recall mode. 2. Press the UP or DOWN keys to select the storage site number. 3. Press MODE key to exit Recall mode. c. Deleting data. 1. Press the ENTER key at the Delete interface to go into Delete mode. 2. Select Delete All or Delete Each mode by pressing the UP or DOWN key. 3. In the Delete all mode, press ENTER key to clear all stored data. Deletion is now complete. 4. In the Delete Each mode, use UP and DOWN key to select data to be deleted. Then press ENTER key to delete. Deletion is now complete. The next set of saved data will automatically move up a slot in the storage site. 5. Press MODE key to exit Delete mode. 11
